Ohhh I'm so glad I've looked at this thread it makes me glad that we always try to pack light.We never take our Mac book we update everything on our return.
In the past DH has taken the camera camcorder and the usual accessories in a Timberland backpack which had a few pockets and extra padding I took the travel documents sweets and snacks etc and DS had his Nintendo DS with games etc.
All our clothes went in just 2 suitcases

and still had a bit of room for anything we bought over there, people in the airport used to say "Is that all you have?"

Quick and easy we get through check-in in about 5 minutes even the hand luggage is scanned in under 10 minutes at the security screening and most of that is waiting in the queue

so far we've not had any problems although DH is always pulled out of the line and scanned again
This year DH has a man's small brown shoulder bag (£8 in Peacocks) for the camera and camcorder and accessories and I have an expandable handbag for the paperwork etc and Ds will have his usual stuff (which will have to be removed from the bag for screening but it's fine).
All our bags will be smaller than the dimensions stated on the VA website and will not take up much space in the overhead storage compartments. We have a few more clothes this year but we'll still only take 2 suitcases
